This study was designed to determine if the decrease in the expression of interleukin 2(IL 2) in spleen lymphocytes after trauma was associated with the changes in the transcription factor NFAT binding activity. Closed impact injury with fracture of both hind limbs in mice was adopted as the trauma model. Animals were sacrificed at the 12h and 1,4,7,10,14 days after injury. Spleen lymphocytes were isolated from traumatized mice and stimulated with concanavalin A, The culture supernatants were harvested and assayed for IL 2 activity. Total RNA was extracted from spleen lymphocytes and assayed for IL 2 mRNA. Nuclear protein was extracted,and DNA binding activity of NFAT was measured using an electrophoretic mobility shift assay(EMSA). The results showed that the DNA binding activity of NFAT gradually decreased , with trough value of NFAT binding activity ,accounting for 41% of the control, observed at 4d after injury. It was closely associated with the decline of IL 2 activity and IL 2 mRNA. These data suggest that the decline in the induction of IL 2 expression is,at least, partially due to the impairment in the activation of NFAT in traumatized mice. Taken together, the results are significant to clarify the mechanism of the decline in the induction of IL 2 expression after trauma.

Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

Assessment or evaluation of student performance in a problem-based learning (PBL) curriculum is difficult to plan or implement.Many medical schools which have switched to a PBL learning format usually use traditional evaluation methods based on factual recalls, which usually has a negative influence on the learning style of the students, thereby reducing the impact of PBL. The purpose of this review is to discuss the various evaluation methods with a particular focus on methods applicable to PBL, so that we can make intelligent use of these methods in our PBL curriculum. In combination with evaluation methods adopted at McMaster University, the article makes an elaboration about them.

Objective To observe the preventive effect of mannatide on infection and relapse of idiopathic thrombocytopenic purura(ITP).Methods One hundred and twenty children with ITP were randomly divided into mannatide treatment group and prednisone control group.Control group venous dexamethasone of 3 d;then treated by prednisone.Treatment group added mannatide tablets for 1 month.The rates of remission clinical blood,platelet,control time,complicated infection and relapse rates were observed.The levels of plasma immunoglobulin(Ig)G,IgA,IgM were determined before and after mannatide treatment.Results The rate of clinical blood,platelet,control time,infection time was not different in 2 groups.The rates of infection complicated and relapse were all significant lower than that in control group.The plasma IgG,IgA significantly increased than that in control group.The plasma IgM had no significant difference.Conclusion Vaccine therapy can be helpful in protecting and decreasing infection,diminishing relapse of children with ITP,and improve the level of IgG,IgA,and thus improve their immune function.

Objective To study the changes of postprandial plasma C-reactive protein(CRP)concentrations after a high-fat meal (800 calorie;50g fat) in patients at high risk of cardiovascular event,and explore the influence of simvastatin on CRP concentration in very short time. Methods 70 patients at high risk of cardiovascular disease were randomly divided into two groups to accept either simvastatin (20mg/d) (SIM group, n=36)or placebo (ROU group, n=34) at the base of routine therapy. All patients received an oral high-fat meal at baseline and one week later. The concentrations of plasma triglyceride(TG), total cholesterol, LDL-cholesterol, HDL-cholesterol and CRP in fasting state and at 4 hours postprandially were measured. Results The postprandial plasma TG and CRP concentrations increased significantly ( P

OBJECTIVETo evaluate the efficacy and safety of Yigan Fupi Decoction (YFD) in the treatment of irritable bowel syndrome with diarrhea (IBS-D) patients.

METHODSA randomized controlled clinical trail was carried out in patients with IBS-D. All patients were randomly assigned to the treatment group (58 cases, treated with YFD) and the control group (58 cases, treated with Pinaverium Bromide Tablet). The treatment course was 4 weeks for all patients. The total effective rate, the stool property and state, the quality of life (QOL), and TCM syndrome efficacy were assessed by IBS bowel symptom severity scale (IBS-BSS), IBS defecation state questionnaire (IBS-DSQ), IBS quality of life questionnaire (IBS-QOL), and traditional Chinese medicine pattern curative effect scoring system (TCM-PES) before and after treatment.

RESULTSThere was no statistical difference in the total effective rate between the two groups (82.76% vs. 77.59%, P > 0.05). The treatment group was superior in the total IBS-BSS integral to the control group (P < 0.05). The total effective rate of improving the stool property was better in the treatment group than in the control group (81.03% vs. 72.41%, P < 0.05). Besides, the number of days for emergent defecation among 10 days was less in the treatment group than in the control group (P < 0.05). The improvement of the total IBS-QOL integral and the total integral of TCM syndrome were better in the treatment group than in the control group (P < 0.01). The total effective rate of TCM-PES was better in the treatment group than in the control group (84.48% vs. 70.69%, P < 0.05).

CONCLUSIONYFD was effective in the treatment of IBS-D patients of Gan-qi invading Pi syndrome, and could effectively relieve bowel symptoms, improve the stool property and the defecation frequency, elevate their QOL, and attenuate Gan-qi invading Pi syndrome with favorable safety and compliance.

Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.
